[RFC] Switching to MemorySSA-backed Dead Store Elimination (aka cross-bb DSE)
...EC2006, there are the following regressions
test-suite...6/471.omnetpp/471.omnetpp.test 321.00 316.00 -1.6%
test-suite...arks/mafft/pairlocalalign.test 64.00 61.00 -4.7%
test-suite...ks/Prolangs-C++/city/city.test 23.00 21.00 -8.7%
test-suite...oxyApps-C/miniGMG/miniGMG.test 69.00 60.00 -13.0%
I suspect those are caused by the few cases that the MemorySSA version does not yet support. Those will need some more investigating, but I think ideally we would not block the switch on them, so we can switch early and address the issues that pop up e...

[RFC] Switching to MemorySSA-backed Dead Store Elimination (aka cross-bb DSE)
Hi,
Over the past six months, a MemorySSA-backed DSE implementation has been added to LLVM and it now covers almost all cases the existing DSE implementation does, plus adding a major new capability: eliminating stores across basic blocks. Thanks everyone involved with reviews, testing & patches!
I think now would be a good time to start working towards switching to use MemorySSA-backed DSE
